RSS 1.0Nuclear Science and Engineering Institute (MU)
The Nuclear Engineering Program at University of Missouri was officially established in 1964 and conferred its first Master of Science degree in that same year. Our mission is to discover, disseminate, preserve and apply knowledge in the area of nuclear sciences and engineering. We interpret our mission here broadly to encompass science and engineering related to neutrons, molecules, photons and other particles.

Development of a novel titanium thermal ionization cavity source for electromagnetic radioisotope separation of samarium and other lanthanide isotopes
(University of Missouri--Columbia, 2022)An available supply of high specific activity radioisotopes was identified by the Department of Energy as a critical priority to the development and eventual deployment of next-generation medical diagnostic and cancer ... -
Novel methods of evaluating materials in extreme environments
(University of Missouri--Columbia, 2022)Three novel experiments were completed to investigate the difference in radiation response between production methods of Inconel 625. Production methods explored were the laser-powder bed fusion additive manufacturing ... -
Effects of beta radiation on nanostructured semiconductor devices for low energy radiation sensing
(University of Missouri--Columbia, 2021)Beta radiation detection currently relies primarily on scintillation detectors. However, the construction of these detectors tends to be large which significantly limits their applicability for field-use. A nanostructured ... -
Influence of inert gases on heat and mass transfer in next-generation nuclear reactors
(University of Missouri--Columbia, 2021)Inert gases cause some unique challenges in nuclear fuel development. In this dissertation, we study the impact of inert gases on the transport behavior in nextgeneration fission and fusion reactors. Uranium--molybdenum ... -
Phonons and thermal neutron scattering in [gamma]-U and U-Mo alloys
(University of Missouri--Columbia, 2020)Elimination of high-enrichment uranium fuels in research and test reactors around the world is one of the many efforts that supports the goal of minimizing proliferation risks. These efforts have pushed for the development ... -

Computation of fission product deposition in aerosols
(University of Missouri--Columbia, 2019)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] High-temperature gas-cooled reactors (HTGRs) generate carbonaceous dust during both normal operations and accidents. The dust particles can be both ... -
Simulation of multiple-component charged aerosol evolution
(University of Missouri--Columbia, 2019)The study of the nuclear source term requires the computation of aerosol dynamics. Solutions to the aerosol general dynamic equation (GDE) are difficult to obtain by analytical or numerical methods when more realistic ... -
Robust and efficient process for acceptance testing of radiation therapy machines
(University of Missouri--Columbia, 2015)The current (legacy) paradigm for acceptance testing (AT), commissioning, and ongoing quality assurance (QA) and quality control (QC) of linac and treatment planning systems (TPS) is extremely inefficient requiring substantial ... -
Direct simulation Monte Carlo for modeling spatially homogeneous multi-component aerosols
(University of Missouri--Columbia, 2018)Nuclear aerosols generated under normal operational and post-accident reactor environments are of particular importance in estimation of the nuclear source term. Several light water reactor aerosol containment experiments ... -
Mesh-free modeling of spatially inhomogeneous aerosols in arbitrary geometries
(University of Missouri--Columbia, 2018)Many issues affect the nuclear source term, one of which is the existence of aerosols. These aerosols are usually simulated with the assumption that they are spatially homogeneous. Making this assumption reduces complexity ... -
